We are starting out with understanding and building hardware; electronics systems and semiconductors where AI can design and create beyond human cognitive limits.\nAbout the Team\nBacked by Silicon Valley’s top investors, Stanford University, and CEOs/Presidents of Google, AMD, Broadcom, Marvell, etc. We are a team of previous Stanford professors, SAIL researchers, Olympiad medalists (IPhO, IOI, etc.), CTOs of Synopsys & GlobalFoundries, Head of Sales & CRO of Cadence, former US Secretary of Defense, National Security Advisor, and Senior Foreign-Policy Advisor to four US presidents.\nWhat You'll Work On\nDevelop and scale MPI+CUDA PDE solvers for electrostatics, charge transport, and electromagnetic field problems on complex 3D IC geometries across multi-node GPU clusters\n\nTune and extend AMG preconditioners, Krylov solvers, and mesh pipelines for performance and correctness at scale\n\nBuild and train neural operators (FNO, DeepONet, GNO, and variants) as high-fidelity surrogates for PDE-based field solvers\n\nDesign simulation pipelines that generate training data for neural operator models - including sampling strategies, mesh handling, and physical consistency checks\n\nValidate everything: analytical solutions, published benchmarks, and cross-validation between field solvers and learned surrogates\n\nRequired\nPhD in computational physics, applied mathematics, computational engineering, or a closely related field\n\nDeep expertise in numerical PDE methods: FEM, FVM, or BEM - weak formulations, quadrature, convergence, error analysis\n\nStrong C++ and CUDA - writing and optimizing kernels, memory hierarchy, multi-GPU programming\n\nMulti-node HPC: MPI, domain decomposition, collective communication, strong/weak scaling\n\nSparse linear algebra at depth: Krylov methods, algebraic multigrid, preconditioning strategies\n\nHands-on experience with neural operators (FNO, DeepONet, or equivalent) - training, architecture design, and evaluation on PDE datasets\n\nSolid understanding of AI for Science methodology: how to design datasets from simulations, handle out-of-distribution generalization, and ensure physical consistency of learned models\n\nStrongly Preferred\nExperience with HYPRE, PETSc, and Trilinos\n\nFamiliarity with multi-node GPU clusters: NCCL, CUDA-aware MPI, NVLink topologies\n\nPublished work in neural operators, physics-informed ML, or scientific HPC\n\nIC design domain knowledge: device physics, semiconductor materials, layout data formats","description_format":"text","description_chars":2601,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["EDA Software","AI Agents"],"lifecycle":[{"event":"open","at":"2026-09-11T02:41:44Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 4","filings_12m":4,"filings_prev_12m":3,"green_card_filings_12m":0,"median_offered_wage_usd":192500,"route":null,"cap_exempt":false,"checked_at":"2026-10-29T16:27:21+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":0}],"liveness":{"score":46,"band":"ok","label":"Likely open","p_open":1,"p_active":0.769,"p_room":0.6,"age_days":256,"expected_fill_days":338,"reasons":["conf:2","velocity","win:late","crowd:"],"computed_at":"2026-11-03T05:54:40Z"},"pay":null,"html_url":"https://alion.io/job/voltai-computational-scientist","json_url":"https://alion.io/job/voltai-computational-scientist.json","meta":{"generated_at":"2026-11-03T06:34:16Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":9086,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":685840},"rest":"https://alion.io/mcp/rest/get_company?id=685840"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvoltai-computational-scientist"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fvoltai-computational-scientist"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fvoltai-computational-scientist"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/voltai-computational-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvoltai-computational-scientist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":699926}},{"tool":"search_jobs","arguments":{"company":"voltai.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":699926},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
